Re: Resurrecting a 1951 Henney-Packard Parts Car

Some clarification after further checking the parts list:

I was incorrect in stating that the 1951 overdrive transmission was different than 1952-54. They are all the same for the standard model cars.

What is different for the Henney cars is the sliding output shaft and flange (Part # 426944, Group 3.236) which mates up with a Mechanics u-joint rather than the Spicer u-joint used on the standard models.The rest of the unit is the same as the other cars including the longer housing. Unfortunately that output shaft is unique to the 1951-54 Hearse & Ambulance chassis so probably almost impossible to find.

It would appear that the transmission from your car was replaced with an earlier type at some point.

The transmission with the shorter case in your photo appears to be an R-11 unit rather than an R-9 as the R-9 has the lockout lever and solenoid on the right side where the R-11 has them on the left.

The missing part an the transmission that you just received is the lockout switch.
